AfterFast, Reliable Sliding & Patio Doors Across Westgate
Sliding and patio door replacement in Westgate, FL typically runs $2,800-$6,500 for impact-rated units, with most jobs permitted through Palm Beach County and completed in two to three weeks from survey to final inspection. We serve Westgate from our South Florida dispatch office, and crews are routinely on-site in the community within a day of the initial call. Call (561) 354-3861 to schedule your free measured survey - the document that becomes your written quote under Haven Clause 1.
Westgate’s unincorporated status means every patio door job routes through Palm Beach County’s building department, not a city office. That distinction changes timelines, paperwork, and product specs. We’ve been navigating it since 2012.

Our Sliding & Patio Doors Services in Westgate
Patio Doors
Standard patio door installation in Westgate ranges from $2,200-$4,000 for non-impact units and $3,200-$5,500 for impact-rated replacements, depending on rough opening condition and frame material. Most Westgate homes built between 1955 and 1975 have original aluminum sliders with single-pane glass that meets no current Florida Building Code standard. We measure the opening, document the frame condition, and specify the replacement before any deposit is taken.
Impact Sliding Glass Doors
Impact sliding glass doors in Westgate are spec’d to Florida Product Approval wind-load ratings, not the stricter Miami-Dade NOA required further south - a meaningful cost difference on every quote. Typical installed cost: $3,800-$6,500 for a standard two-panel slider in a 6-foot opening. We source impact-rated laminated glass with low-E coating and argon fill from manufacturers including CWS and ES Windows, selected by performance tier and price range, not by what happens to be in stock. The interlayer holds the glass in place under impact, and the low-E coating cuts solar heat gain on west-facing rear elevations common in east-west oriented Westgate lots.
Sliding Glass Door Replacement
Sliding glass door replacement in Westgate often requires more than swapping the sash. The original aluminum buck and jamb on these CBS ranch walls corrodes or pulls out of plumb over decades of humidity and thermal cycling. On a 1968 CBS ranch off Purdy Lane in Westgate, our crew pulled a rusted aluminum slider and its rotted buck to find the rough opening out of plumb by nearly an inch. We squared and prepped the opening, set an impact-rated sliding glass door with laminated glass interlayer and low-E glass on a PGT frame, tied it into the block, and passed the Palm Beach County inspection on the first visit - the homeowner’s wind mitigation report then qualified the opening for the windstorm credit under Florida Statute 627.0629. Full frame-out replacement adds $800-$1,500 to the base scope but is non-negotiable when the opening won’t anchor true.
Impact French Patio Doors
Impact French patio doors bring hinged operation to Westgate homes where a slider’s track has failed or where the homeowner wants the full opening clearance for access to patios, pools, or detached structures. Installed cost typically runs $4,500-$7,200 for a standard pair in a retrofitted opening. Because French doors impose lateral load differently than sliders, the frame-out and anchoring into CBS block is even more critical on Westgate’s non-standardized rough openings. We specify ECO Window Systems and Mr-Glass lines for this application when the opening size and wind-load calculation support them.
Screen Door Installation
Screen door installation in Westgate ranges from $350-$750 for a standard sliding screen on a new or existing patio door unit. On older Westgate homes, the original screen track is often bent or corroded beyond salvage and gets replaced as part of the full opening retrofit.

AfterTrusted Brands We Service in Westgate
We draw from eight verified manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - specified by what the opening requires, not by what is in stock. For Westgate’s non-HVHZ status, we frequently recommend CWS and ES Windows impact sliding door systems that carry Florida Product Approval at the wind-load ratings Palm Beach County requires, without the cost premium of Miami-Dade NOA certification. Parts and hardware for these lines are stocked regionally, so warranty or service calls in Westgate don’t wait on cross-state shipping. Our Sliding & Patio Doors team selects the frame material, glazing package, and hardware finish based on the measured survey, not a showroom pitch.
Common Sliding & Patio Doors Problems We See in Westgate Homes
- Corroded aluminum buck and out-of-plumb frame on CBS walls. The original aluminum buck and jamb corrodes or pulls out of plumb on mid-century CBS walls, so new sliders can’t be anchored true without full frame-out replacement - a common Westgate callback if skipped. We document frame condition during the measured survey and write the prep scope into the quote.
- UV and humidity degradation on west-facing rear elevations. West-facing rear patio door frames degrade fast under year-round UV and humidity, causing vinyl or aluminum frame distortion and seal failure long before the impact glazing itself fails. We see this most on east-west oriented Westgate lots where the rear patio catches afternoon sun.
- Failed or missing wind mitigation documentation. Palm Beach County carriers are actively non-renewing policies on homes without FBC-compliant impact windows and doors. A non-compliant slider can block your windstorm credit and trigger a non-renewal notice. We provide the product approval documentation and installation certificate needed for the wind mitigation form.
- Unpermitted or improperly permitted installs flagged at inspection. Unpermitted or city-style permitted installs get flagged because Westgate runs on Palm Beach County’s submittal and inspection cadence - missing county-specific paperwork stalls or fails final inspection. We pull the permit, schedule the inspection, and don’t close the job until the county signs off.

FAQs - Sliding & Patio Doors in Westgate
Westgate is unincorporated, so every patio door replacement permit routes through Palm Beach County’s building department - not a city office. The county has its own submittal requirements, inspection cadence, and documentation standards that differ from municipal timelines. We pull the permit, schedule the inspection, and manage the paperwork as part of our standard scope. Call (561) 354-3861 to schedule your free measured survey.
Westgate sits outside the Miami-Dade/Broward High-Velocity Hurricane Zone, so impact sliding doors here need Florida Product Approval at Palm Beach County’s wind-load rating - not the more restrictive Miami-Dade Notice of Acceptance. That spec distinction lowers product cost on most quotes. We verify the rating on every product data sheet before specifying it. Call (561) 354-3861 for a written quote with the exact product approval number documented.
Westgate’s 1950s-1970s CBS ranch homes were built before standardized window and door sizing, and the original aluminum bucks corrode and pull out of plumb over decades. A new impact slider cannot be anchored true into masonry that’s out of square. We document frame condition during the measured survey and write any necessary frame-out work into the written scope before quoting. Skipping this step is a common callback. Call (561) 354-3861 to have your opening assessed.
Yes - if installed with proper documentation. Florida Statute 627.0629 requires insurers to apply windstorm mitigation credits for FBC-compliant impact openings. We provide the product approval documentation, installation certificate, and photo record needed for your wind mitigation inspection. Several Westgate homeowners we’ve worked with near the Westgate Recreation Center area used our documentation to secure credits and avoid non-renewal. Call (561) 354-3861 to discuss your specific policy situation.
Low-E impact glass with argon fill typically reduces solar heat gain by 40-60% compared to single-pane aluminum sliders, which is significant on west-facing rear elevations in Westgate’s climate. The exact savings depend on your home’s orientation, insulation, and HVAC efficiency. We specify the SHGC and U-factor on every quote so you can compare performance numbers directly. Call (561) 354-3861 for a free estimate with documented glass specs.
